摘　　要：为了进一步研究园林植物叶片中化学成分与抗病虫害的关系,对合肥市9种常见园林植物的病虫害发生情况进行调查、统计和分析,并对这几种植物抗病虫害能力与叶片中总黄酮和多酚含量的关系建立数学模型。研究结果表明,在一定范围内,参试植物叶片中只有多酚的含量与叶片的抗病虫害能力能形成二元回归关系,说明叶片中多酚含量越高,其抗病虫害能力越强。In order to learn relation of chemical constituents in garden plant leaves and diseases and insect pests resistance,occurrence status of diseases and insect pests in 9 common garden plants was investigated and analyzed in Hefei City,and a mathematical model was established,which reflected the relation of total flaconoids and polyphenols contents in leaves and disease and insect pests resistance.The results showed that a binary regression model could be established only reflecting the relation of polyphenols contents in leaves and disease and insect pests resistance.That was,the higher polyphenols content in leaves,the stronger diseases and insect pests resistance.
